Abstract
Diapause in the pink bollworm, Pectinophora gossypiella, is a quantitative genetic character that is in turn regulated by external environmental factors. A naturally occurring non-diapause strain of the insect from south India and two diapause strains from Arizona (U.S.A.) were used in crosses to study the inheritance of diapause. The F1 progeny expressed a diapause response intermediate between the two parents and no clear dominance was evident for the non-diapause character. It was not possible to classify the phenotypes of backcross and F2 progeny in accordance with simple Mendelian ratios. Comparisons of reciprocal crosses indicated that the progeny from male parents of the Indian strain usually had a lesser incidence of diapause. Such sex related differences were more evident in F2 progeny and backcrosses. It is therefore concluded that diapause in the pink bollworm is inherited in a complex way and that non-diapause is not completely dominant over the diapause trait. The study also indicated that incomplete dominance for non-diapause involves a sex-linked gene.
